Ultradyne USA
The Ultradyne USA C4 Offset Folding Front Sight transforms how you shoot AR-15s by solving a core problem with traditional iron sights: they block your view of the target. This innovative offset folding front sight uses Ultradyne's Dynalign technology to create a unique circle-within-circle sight picture. Instead of a solid post, the C4 features a hole drilled through its center that aligns concentrically with a compatible rear sight, letting you see your target while perfectly aligned for accurate fire.
The 45-degree offset mount means the C4 won't interfere with your primary optic, making it an ideal backup or secondary sighting solution on modern tactical or hunting ARs. When you don't need it, the sight folds flat against the rail to minimize profile. Built tough from a combination of 4140 chrome-moly steel and 7075 aluminum, it's treated with salt-bath nitride and anodized-black finishes for durability in the field. At just 1.2 ounces, it adds minimal weight to your setup.
Whether you're running a scoped AR for long-range hunting, setting up a tac-rifle for competition, or building a do-it-all defensive carbine, the C4 Offset Folding Front Sight is a smart choice for shooters who want the speed and simplicity of irons without sacrificing sight radius or optic real estate.
